(c1. se 1s) The invention relates to a washing machine cylinder construction, and more particularly to the connection of the perforated ribs to the heads and partitions of ,the cylinders of washing machines.

The primary aim of the present invention is'to provide combined unitary yoke members with longitudinally disposed perforated metallic ribs especially adaptable and designed for use in washing machines having cylinders of the wooden type, whereby the benefits and advantages heretofore obtainable in the metal type of washing machine cylinders are made available in the wooden type.

Another aim of the present invention is to provide the combined unitary yoke members with the longitudinally disposed perforated metallic ribsin wooden washing machine cylinders so that the life and efficiency of such cylinders are materially greater than that of cylinders entirely made from wood. a

A further aim of the present invention is to provide a metallic yoke and rib. construction for Wooden cylinders with which replacement of the associated wooden structure-can be had with dispatch, yet it should be apparent that the yoke members and ribs may be used indefinitely.

A still further aimof the presentinvention is to provide a yoke and rib construction for the cylindersof washing machines which is of novel form-and possesses simplicity and at the same time obtains speed and efficiency equal to that of all metal cylinders frequently employed in washing machines.

A still further aim of the present invention is to provide a yoke and rib construction, which is extremely simple in make up, strong, durable,

thoroughly reliable and efficacious, and inexpensive to manufacture.

With above and other aims in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illus trated in the accompanying drawings showing the preferred embodiment of the invention andpointed out in the claims hereunto appended.

In the accompanying drawings.

Similar reference characters indicate corresponding parts throughout the several views the drawings. Referring to the drawings in detail, .A, designates generally a washing machine cylinder, in

thisinstance including a cylindrical body 10,

formed as usual from a'series of wooden staves orplanks longitudinally disposed and united with ends or heads 11, these in this'instance being also made from wooden-planks. Encircling the body at each end or head 11, is a hoop or meta band 12, which reinforces the. cylinder..

Disposed longitudinally of the cylinder A, are substantially U -shapcd or 'V-shaped perforated metallic ribs 13, which are radially disposed equidistantly from each other and open outwardly of said cylinder, it being understood, of. course, that there may be anynumber of ribs to a cylinder.

a yoke member comprising an unbroken frame 14, correspondingly shaped to the cross-sectional,

formation of the rib, with its center open as at 15, to accommodate the rib. This frame 14, is formed with an outer saddle 16, with. the ends of the latterv extended beyond the frame and with its outer surface conforming to the'outer.

surface of the cylinder, while the ends at the inner sides thereof are beveled as at 17, to fit into corresponding notches 18, formed in planks adjacent thereto of the body 10, of said cylinder, and in this manner the frame overlaps these planks, theheads or ends 11, of the cylinder A, being cut into correspondingly to the size'of the yoke members at their peripheries for the fitting saddle 16, sufficiently to accommodate the notched I staves or planks next thereto of the cylinder A, while the planks of the heads 11, at the edge of the out-away portions therein fit snugly between the flanges 19, and 20, of said frame 14, and in this manner the latter are assembled within the head. 7 I

The hoop or band 12, is riveted or bolted as at 21, to the saddle 16, of the frame 14, while the rib 13, is also riveted at 22, to said frame, to effect a unitary structure. The frame 14, is cast or otherwise formed from metal, while the rib 13, is preferably made from sheet metal, yet it may be molded, cast, or otherwise formed if found desirable.

It will be apparent that the ribs 13, with their complemental frames 14, are readily removable Each end of the respective ribs 13, fi ts within forated ribs 13, of the present invention is toallow the water to rapidly penetrate the clothes during washing of the same.

What is claimed 'is: c

1. The combination with a wooden cylinder for a washing machine having end walls, of a perforated metallic rib, and yoke members embracing and rigidly secured to the ends of said rib and seatable within the ends of said wooden cylinder, said yoke members having divergent side walls, saddle portions connecting the latter at their flaring ends, and outwardly-open flanges on said side walls and the divergent ends of said yoke members wherein their correlated end wall of said wooden cylinder is adapted to normally seat.

2. The combination with a wooden cylinder for a washing machine having end walls, of a perforated metallic rib, a yoke member embracing and 3'. The combination with av washing machine cylinder of the wooden type having end walls provided with peripheral notches, of a perforated metallic rib, and yoke members rigidly secured to and embracing the ends of said rib adaptable for seating in said peripheral notches, said yoke members having divergent side walls, saddle portions connecting the latter at their flaring ends, and outwardly'open flanges on said side walls andthe divergent ends of said yoke members wherein their correlated end wall of said wooden cylinder is adapted to normally seat.

4. The combination with a wooden cylinder for a washing machine having end walls, of a series of perforated metallic ribs, yoke members embracing and rigidly secured to the ends of said ribs and seatable within the ends of said wooden jcylinder, each of said yoke member having divergent side walls, a saddle portion connecting the latter at their flaring end, and outwardly open flanges on the side walls and the divergent end of the yoke member adapted to receive their correlated end wall of said wooden cylinder, and hoops embracing theends of the cylinder and attached to the saddle portion of each of said yoke members for retaining the latter in seated relation in their correlated cylinder ends.

5. A yoke member of the class described having divergent side walls, a, saddle connecting the Walls at their flaring end, and outwardly open flangeson said side walls. i a

6. A. yoke member of the class. described having divergent side walls, a saddleconnecting the walls at their flaring end and extending beyond the same, and outwardly open flanges on said side walls, said flanges terminating in spaced relation to the extending ends of said saddle to form notches therebetween.

7. A yoke member of the class described having diverging side walls, a plate connecting the walls at one end thereof, an arcuate saddle connecting said walls at their flaring end, and outwardly open flanges on said walls and plate.

8. A yoke member of the class described having diverging side walls, a plate connecting the walls at one end thereof, a saddle connecting said walls at their flaring end and having its ends extending beyond the same, said saddle having its outer surface conforming to the arc of a circle, and outwardly extending flanges formed in spaced parallel relation upon said side walls and plate, said flanges terminating in spaced relation to the extending ends of said saddle to form notches therebetween.
